Walk-on rooflights in Guildford: what is involved?
Our walk-on rooflights service in Guildford covers structural glass you can stand on, set flush into terraces and floors. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Across the South East, single-storey kitchen extensions on 1930s semis and post-war detached houses are where most flat rooflights and lanterns go. In Guildford, as anywhere, walk-on rooflights are the usual choice for terraces where the light below matters as much as the space above.
Guildford sits about 6 km from Godalming and 9 km from Woking, and we cover the whole GU1 postcode district and the roads in between.
Options we can specify in Guildford
- Integrated in paving pedestals or a timber deck

Consents for walk-on rooflights in Guildford
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge. Listed buildings need listed building consent, flats have no householder permitted development rights, and an Article 4 direction can remove the rights in some conservation areas.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
Read the planning permission guide before you commit to a design.

Questions about walk-on rooflights in Guildford
Is the glass slippery?
Walk-on glass has an anti-slip finish, usually a ceramic frit or etched pattern. Like any outdoor surface it needs cleaning to stay effective.
Will it sit flush with my paving?
Yes — the unit is set on its own upstand so the glass finishes level with the surrounding paving or decking.
Does it need a structural engineer?
Often, yes. Where the unit sits on new or altered structure, an engineer confirms the support and the manufacturer confirms the glass.
Do I need to be at home for the survey in Guildford?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Guildford?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
